Textured grooves on the side of the bottle ensure a firm grip and enable it to fit that much more securely in water bottle pockets and sleeves as well as standard bike cages. An extra side opening makes the bottle easy to fill and clean.The Kicker Valve cap is what really sets the bottle apart from others. The valve itself is placed off center to provide more ergonomic access. The welded silicone valve is surprisingly durable and opens easily with either your fingers or your teeth.
